LIGHTING- DEVICE FOR GAS-BRNERS. l

- of simultaneously lighting all the gas rings or burners within the range.

'lhe invention consists of novel features and parts and combinations of the same as will be more fully described hereinafter and then pointed out in the claims.

, A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a plan view of the lighting device as applied to a gas range, part of which is shown broken out; Fig. 2 is an enlarged sectional elevation of the lighting device on the line 2 2 of Fig. l; Fig. 3 is asectional plan view of the same on the line 3--3 of Fig. 2*; and Fig. fl is a sectional plan view of the same on the line 4 4 of Fig. 2.

The gas range A to which thelighting device is shown applied is provided with the usual gas ringsor burners B, B', B2v and B3, supplied with gas by branch pipes C, C', C2 and C3 connected with thegas supply pipe D usually located on the front of the range. Each of the branch pipes C, C, C2 and C3 is provided with a valve E for controlling the flow of the gas to the corresponding gas y ring or burner B, B, B2 or B3.

A pipe F extends transversely between the burners B and B', that is, underneath the grid of the gas range A, as plainly indicated in Fig. l, and the pipe F supports at its inner end a multiple burner Gand is connected at its outer end with a valve H having its casing H. attached to the gas supplypipe D so that gas can pass from the supply 'pipe D by way of the valve H and the pipe F to a multiple burner G arranged approxi mately equal distances from the centers of the gas rings B, B', B2 and B3. The multiple burner G is provided with individual burner Specicaton of Letters Patent.

as hereinafter more fully explained, then the llames from the said burner openings G', G2, G3 and G4 extend to the gas rings B, B',

B2 and B3 whereby the gas issuing from the said burners is'ignited whenever the corresponding valves E are opened. I

l The valve H is provided with a longitudinally extending bore H2 -intersected at right angles by a conical valve seat Hs on which is seated a conical valve plug I provided on its base with a cylindrical extension I having a recess I2 vin the under side, into which extends the upper end of a coil spring J seated on a cap K screwing in the bottom of the valve casing H. The spring J normally returns the valve plug yIto its seat H3 thus disconnecting the multiple burner GrI from the supply pipe D. c The upper end of the valve plug I is provided with a pin I3 engaging a recess inthe lower conical end L -of the cylindrical body of an actuating valve L mounted to slide in a bearing H4 arranged in the valve ,casing H. The valve L is provided witha shank L2 carrying a fingerpiece L3 adapted to be engaged by a linger of the operator/to permit the latter to press the valve L downward so that the valve plug I is moved in a like direction whereby the valve plug I opens the bore H2 to allow the gas to flow from the supply pipeD through the bore H2 and' pipe F to the multiple burner G. When the pressure on the fingerpiece L3 is released the valve L and the valve plug I return to their normal positions by the action of the spring J. The conical end L of the valve L is adapted to be seated on a conical seat H5 formed on the lower end of the bearing H so as to close the bearing when opening the valve plug I to prevent leakage of gas by way of the said bearing H4. The upward movement of the vale L is limited by a set screw N screwing in the valve casing H', as plainly indicated in Fig. 2.

By reference to Fig. 2, it will be noticed that the smallends of the valve seats H8 and H5 are connected with each other, and when the valve L is pressed downwarduntil the conical end L 'is seated on its seat H5 then the valveplug I is moved into open position, but its opening movement is limited as the conical end L cannot move farther los spring J is notJ liable to be broken.

In order to ignite the gas issuing through l theinultiple burner G use is made of a constantlyvburningfpilot light and for this purpose the following arrangement is made.

A by-passjvO leads from the bor wHv2 at the pointfbetweenthe valve plug I and the sup-v ply pipe D, and the amount of gas passing through thisfby-pass O is controlled by a set screw B' (see Fig. 4l).- The terminal of the'by-passy O connects with a short pipe Q,

attached to the valve 'casing H', and thel said short pipe Q extends into the enlarged end Q of a pipe Q? which extends through the ypipe Fand its elbow F to then bend. upwardly to finally terminate in close prox! imity to the multiple burner. G. It Will be noticed .thatby the arrangement described gas will at all times pass by Way of thesupply pipe D, the bore H2, by-pass O, pipes Q,

"and Qf? to the terminal of the pipe Q2 at which the gas is burned, to ignite the gas issuing from the multiple burner G Wheneverfth'el valve plug I is opened as previously explained.

The'multiple burner G and the terminal A ofthe pipe Q2 are inclosed Within a hood or deflector R provide'd in its side Wall with openings R', R?, B3 and R4 in register With the 'burner openings G', GZ, Galand G, as plainly indicated in Fig. 3. The hood or `deector R is removably .seated in a cupshaped base R5 attached to the upper end of -the tube Fby the bodyG5 of the multiple burner G, Which body screws into the upper end ofthe elbow F. The bottom of the base R5 is provided with a number of openings R to permit air to pass into the hood R and to the multiple burner G. The hood or defiector R is provided in its sidewith a depression R7 fitting onto an inwardly extending struck-up lug R8 formed on the side of the base Riso as to hold the hood R from turning and to hold the openings R, R2, R3 and R4 in register with the burner openings With a view to move the valve plug I into.

open position. Gasv novi flows from the supply pipe D to the multiple burner G, as previously explained, and the gas issuing through the burner openings G', G2, G3 and G4 isV ignited by the pilot light and the iames are directed to the gas rings B, B, B2 and B3 to ignite the gas issuing-therefrom. Thus by the arrangement described the gas rings can be readily ignited Whenever their corresponding valves areopened by the use of auxiliary gas ames directed onto the gas rings by the multiple burner G so that the user of the gas range is not liable to burn the hand as when lighting the .gas ringsv in the ordinary'v manner, avoiding the dangerous use of matches and Waste of gas.
